To me this fragmentation is one of the strongest suits. Instead of putting everyone who is interesting in technology together, (which is an very large group of people), you can subdivide people. Take AI/LLMs for example. There's a group of people who is really interested by them and tries to use these technologies as much as possible. Theres also a group of people who is very critical of the harms and negative side effects of LLMs. Instead of mashing them together in a single community, both can now discuss the same news from their own standpoint.

And no, I'm not concerned about filter bubbles. I think the problem is the opposite, the idea that we have to force people in the same space who do not want to be together in the same space. Just like we dont do that in real life, people should gather around with the people they want to be with.

Right now it might be a problem, but in the long term the communitys work it out themselves, reddit also had 10 different (general) memes subreddits.

As long as the instances are federated you can find their communitys pretty easily and participate there

I just visit the top Lemmy instances, sort by local category, and follow the ones I like on each instance. It doesn't matter if I follow 4 different channels called !technology cause I'll just get them all in my feed. I'm following self hosting on both lemmy.ml and lemmy.world and I get posts from both. I couldn't care less where it comes from, as long as I'm following I'm good to go.

There are many sites and list of large Lemmy servers right now. Just check out beehaw, lemmy.ml, lemmy.world, sh.itjust.works, etc.

You're right on that part. Federations works great with mastodon and its instances made of individuals directly interacting with each other's accounts.

But when it comes to interacting though communities already spread through instances, not only it makes it hard for people to follow all these duplicates, but it threatens the very principle of federation in a certain way. Because most people will eventually subscribe to the biggest community for each subject (tech, nature, photo), which often turns out to be hosted on the biggest instances...and that is centralization once again.

A solution could be for users to gather all the communities they subscribed to around topics. Then your feed would be a mix of these topics' groups and singles /c. Twitter does that similarly with its List feature.

Ultimately this is a problem that's never going away until we replace URLs. The HTTP approach to find documents by URL, i.e. server/path, is fundamentally brittle. Doesn't matter how careful you are, doesn't matter how much best practice you follow, that URL is going to be dead in a few years. The problem is made worse by DNS, which in turn makes URLs expensive and expire.

There are approaches like IPFS, which uses content-based addressing (i.e. fancy file hashes), but that's note enough either, as it provide no good way to update a resource.

The best™ solution would be some kind of global blockchain thing that keeps record of what people publish, giving each document a unique id, hash, and some way to update that resource in a non-destructive way (i.e. the version history is preserved). Hosting itself would still need to be done by other parties, but a global log file that lists out all the stuff humans have published would make it much easier and reliable to mirror it.

The end result should be "Internet as globally distributed immutable data structure".

Bit frustrating that this whole problem isn't getting the attention it deserves.
